Abstract

PURPOSE:To prevent occurrence of ears, in winding a strip round a roll after annealing, by pressure-contacting the strip with a crowned roll from the outside immediately before winding. CONSTITUTION:0.3-0.5mm thick austenitic stainless steel strip 1 is wound round reel 3 as coil 2. At this time, strip 1 is pressure-contacted with crowned roll 4 whose crown made of elastic body such as rubber is about 2-6mm at a position immediately before winding as coil 2. Pressure contacting position (a) with roll 4 is changed as coil 2 becomes thicker, so by controlling hydraulic cylinders 6, 7 the position of roll 4 is adjusted. Thus, a yield lowering due to occurrence of ears in the wound strip can be prevented.
